MUSIC-SHEET FOR MECHANICAL MUSICAL ENSTRUENTS.

SPECIFICATION forming part of Letters Patent No. 224,715, dated February 17, 1880. 4 Application at May a, 1m.

To all whom it may concern:

Be it known that I, ELIAS .P. NEEDHAM; of New York, in the-county and State of New York, have invented certain-new and useful 5 Improvements in Music-Sheetsfor use in Mechanical Musical Instruments, of which the following is a specification.

The perforated or recessed music-sheets usually employed in mechanical musical instruments are generally permanently secured at one end to ainusieroller upon which the sheet is wound before being placed in the instrument, and are permanently secured at the other end ,to a take-up roller upon which thesheet is wound as it passesthrough the instrument, requiring a separate music-roller and take-up roller for each music-sheet.

The object of this invention is to produce a music-sheet which may be readily attached to and detached from a take-up roller, thereby dispensing wit-h a separate take-up roller for each music-sheet, and eifecting a saving in cost and in the room required for packing said music-sheets for shipment.

To this end my invention consists in the .combination, with a perforated or recessed music-sl1eet,-of' a slotted take-up roller which receives within it one end of said sheet, and a pin which is attacn'ed to the end of the sheet and securesthe sheet to-the roller by being received within the slot thereof.

It consists, also, in details and combinations of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 represents a plan of a music-roller, a musicsheet wound thereon, and a take-up roller detachabl y secured thereto. view of the under side-thereof; Fig. 3, a 1011 git-udinal section through the take-up roller; Figs. 4 and'5 t'raiis'vci'sc sections-through the music and take-up rollers, illustrating the manner of attaching the music-sheet; and Fig. 6, a longitudinal section through a take-up roller of slightly modified form.

Similar letters of reference designate corresponding parts in all the figures. I l A designates a music-roller provided with .bear-ingsc for insertion in a musical instrn-.

ment, and B designates a perforated or re cessed music-sheet,represented as permanently secured to the music-roller A at one end and Fig. 2 represents a wound thereon preparatory to being placed in a musical instrument. I) designates a takeup roller upon which the musicsheet is' wound after passing through the instrument.

I have represented the music-sheetas furnished with a loop, b, at its. end, through which a pin, a, may be inserted, roller 0 as provided witha slot, d, through which the loop 1) passes and in which the pin 0 rests. This pin 0 is preferably composed of a small straight stick of wood, and when inserted into or attached to the sheet occupies a position parallel with theplane of the sheet when the latter is straightened out.

At the ends of the slot at are shoulders d, formingstops, against which rest the ends of the pin 0, which project in opposite directions beyond the edges of the paper, the said shoulders preventing the pin from being drawn through the slot. The pin a is shown as permanently attached to the take-up roller by a cord, a, resting in a groove, j, in the said takeup roller 0, and may be detachab-ly attached to the music-sheet by inserting it in the loop b in the end thereof.

As the pin 0 rests within the slot at entirely below the surface of the take-up roller, it offers no obstruction to the free winding of themusic-sheet upon the said take-up roller.

In attaching the roller the loop 11 is first passed through the slot d. The pin cis then inslot, as rep-' serted, and finally drawn into the resented clearly in Fig.6.

In Fig. 6 I have represented the pin a as permanently attached to the music-sheet 'B and the slot at in the take-up roller 0 so formed that upon the; pin 0 being tilted, as represented in dotted outline in Fig. 6, it may. be drawn through the saidroller, thereby detaching the latter from the musicsheet.

By my invention I .dispense with the perand vthe take-up manently-attached take-up rollers secured to each music-sheet, one roller only being necessary for each instrument, instead of one for each music-sheet, as heretofore.

What I claim as my invention, and desire to secure by Letters Patent, i's-- 1. The combination, with a perforated or recessed music-sheet, of a slotted.take-up roller which receives within it one end of said sheet, and. a pin whichis attached to'the end of the sheet and secures the said sheet to the roller by being received Within'the slot thereof,

substantially as specified.

I projecting beyond bath edges-thereof; mid-the take-upv roller 0, provided with a slot, d, for

the'passage of thesheet, and with shculders d at both ends of the said slot, forming beam 10 .iugs for the portions of the ,pin projecting beyond the edges of the sheet, substantially-as specified.
